BOLSTER FOR SPINNING-MACHINE SPINDLES.

SPEGIFCATION forming pari'. of Lettexs Patent No. 338,238, dated March 16, 1886,

Application filed July 7, 1354.

To @ZZ whom it may concern:

Be it known that I, HENRY F. WooDMAN'cY, of VVhitinsville, in the county of Vorcester and State of Massachusetts, have invented a new and useful Improvement in Bolsters for Spinning-Machine Spindles; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of the invention is to form a support for a spinning-machine spindle in which the bolster and step are supported, so that when running the spindle may adjust itself to the varying yarn-load.

Another obj ect of the invention is to secure more perfect lubrication of the spindle.

The invention consists in the peculiar and novel construction of the bolster and bolstercase, as will be more fully set forth hereinafter.

Figure 1 is a sectional view of the bolstercase, the bolster, and sleeve-whirl, showing the spindle in elevation. Fig. 2 is a sectional view of the combined bolster and step, and Fig. 3 is a sectional view of the bolster-case.

ln the drawings, A is the bolster-case provided with the lange a, which rests on the bolster-rail ofthe spinning-niachine,and the screw-thread a', on which a nut is placed to secure the bolster-case to the rail. The tube or2 extends above the flange a and above the oil-cup a3.

b is an elastic and sound-deadening ring, forming a support, made, preferably, of cork; but any other material having the capacity to yield and which does not transmit sound may be used in place of cork.

The bolster B, provided with the step at its lower end, is of less diameter than the interior of the bolster-case, so that the lubricant,

can freely iiow around the bolster, and the oil or other lubricant, raised by the revolution of the spindle to the cup Z22 at the upper end of the bolster, iiows down through the holes c c between the tube a2 and the bolster, entering the bolster again by the holes c c in the bolster-case and step, thus insuring a free circulation of the oil and thorough lubrication of the spindle. Any oil passing between the tube a2 and the sleeve b3 and carried to the oil-cup Serial Xo. 137,013. (No model.)

a3 is carried back into the bolster-case' by the hole at. (Shown in Fig. 3.)

The bolstercase may be made of much larger internal diameter than the outer diameter of the bolster, either in part, as is shown in the drawings, or the whole length, so that a large quantity of oil may be held in the same and thereby the spindle be lubricated for along time.

The sleeve b3 and the ange b4, which forms the cap for the oil-cup, form part of the bolster B, and support the combined bolster and step, with the spindle resting on the elastic ring b and tting loosely on the outside of the tube c2. The sleeve b3 bears against the tube a2 holds the bolster-tube concentric in the bolster-case and resists the side pull of the band on the whirl d. l

The bolster B is connected with the sleeve b at the upper end by a small quantity of metal, that the lower step end of the bolster B may yield slightlyin the effort of the spindle and bobbin to adj ust themselves, such yielding being restrained by the spring of the metal, so that when the disturbing force ceases the bolster B will return to its true axial. position. This automatic adjustment of the spindle, bolster, and step is facilitated by the elastic ring b, on which the bolster and spindle are supported, and, as this ring-support is placed of the spindle, the` elastic ring b, while it allows the bolster and spindle to adj ust themselves to the center of gravity of the yarn-load, offers a springy resistance to such force and returns the bolster and spindle to its true axial position when the disturbing force changes or ceases. The whirl d is formed on the end of the sleeve d', which is secured to the spindle E and rotates with the same. By this improved construction the bolster is suspended within the bolster-case from a point above the center of the whirl, so the spindle may readily find its true center, while the spindle runs without the jar and noise incident to other spindles. The bolster-step and spindle can adjust themselves under sufficient restraint to the yarn-load, and thus prevent all tendency to gyration caused by an unequal yarn-load, and, as the bolster is suspended in the bolster-ease and surrounded by an oil-space, the

a considerable distance from the axial center IOC lubrication of thespindle is more perfect and the circulation of the 'oil more uniform.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the bolster-euse A, provided with the upwardly-extending tube a2, of the bolster provided with the sleeve b3, and ange bt, constructed to support the bolster and step Within the bolster-ease, as de# scribed.

2. The combination, with the bolster-case A, ofthe combined bolster and step B, provided. at its upper end with the sleeve b3 and the lange b, constructed to forni a cover for the oil-cup and support the bolster and step Within the bolster-case, as described.

3. The combination, with the bolster-case A, provided with the upward-extending tube a2 and the oil-cup a3, of the combined bolster and step B ,Mprovidedyith the sleeve b3 and iittnge b, and the elastic ring b, constructed to form a yielding sound-deadenig support for the spindle, as described.

4. The combination, with the combined bolster and step B, provided with the sleeve b3 and liange b4, and the bolster-case A, provided with the oil-cup a and tube co2, of the spindle E, provided with the sleeve-Whirl d, the whole constructed to suspend the bolster Within the bolster-case from u point above the center of the Whirl und allow the spindle to nd its true center, as described.

In Witness whereof I have hereunto set my hand.

HENRY F. VOODMANCY.
